IMPRovEMEN'riN HORSE-POWERS.

Specification forming part of Letters Patent' No. [83.572, dated October 24, 1876 application filed September 22, 1876.

To all whom it may concern:

Be itl known that I, IsAAc JOYNEB, of J onesborough, county of Tippah and State of Mississippi, have invent-ed a new and useful Improvement in Horse-Power, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a horizontal section on line ava', Fig. 2; and Fig. 2 a side elevation, partly taken in section, on line y y, Fig. 1.

Similar letters of reference indicate corresponding parts. A

The invention relates to improvements in horse-powers, by which the power is 'fully controlled and transmitted with little loss, for running machinery of all kinds; and the invention consists of a wheel with spider-frames that support an interior drum or cylinder, of sufficient size for the horse to walkv in, the power being transmitted by a friction-wheel, in contact therewith. One of the radial frames su pports anoutermost circle that forms, with suitable levers and frictionshoe, an et'- In the drawing, A represents a wheel, constructed of two parallel spider-frames, A' A",

hubs of a shaft, B. The shaft B turns in bearings of a strong supporting-frame, of any suitable construction. 'lhe spider-frames A' A" are connected, at the ends of their arms,

one spider-frame to such length as to support ring-shaped fra-mes b, one being attached to the arms of the spider-frame, and to the lateral pieces, while the other is applied to the frontends of said pieces. These ring-shaped frames b support closely said lateral strips d, of sut'tcient thickness to form a drum or cylinder of such diameter that one or two horses The interior drum-pieces d are additionally stiftened' by an interior braceway, e, and a face-ring, c'. A

A friction pulley or wheel, 0,'is supported in bearings O', hung to the main frame in such a manner that it forms an intimate contact with the inner surface ofthe cylinder back of working horse or horses, and transmits the power by a shaft, D', wheel D, and suitable belting to the machine, mill, or apparatus to be driven.

The central spider-frame A", intermediately between between drum and outer spiderframe A', -is encircled by a circumferential wheel or band, E, of wood or other suitable material, against which a brake-shoe, F1, attached to a lateral cross-rod, F, is pressed by means of an upright lifting-lever rod, G', and an operating hand-lever, Gr.

The cross-rod F is hung by a pin, at one end, to the slotted lower end of lever-rod G', and supported in a guide-bearing, F2, at the opposite end.

By pressing the lever Gr the brake-shoe is raised, and brought to bear against the circurnt'erential brake-wheel or band E; so that in this manner the speed may be regulated, and, if desired, entirely interrupted atv the will ot' the operator.

In this manner a strong, simple, and con convenienbly-controlled horse-power, for various purposes, is obtained.

Having thus described my invention, l claim as new and desire to secure by Letters Patent-v l. A drum or cylinder for horse-powers, constructed ot' supporting spider-frames, with outer lateral brace-pieces'carrying the drumframe, substantially in the manner and for the purpose set forth.

2. The combination of a drum or cylinder, at the inside of supporting spider-frames and outer brace-pieces, with a friction pulley or wheel, brought in contact therewith, and being mounted on the driving-shaft, substantially as herein specied.

3. A circumferential band or wheel, E, mounted around the spider-frame A', in combination with brake-shoe F1, and operating lever mechanism, to regulate speed of wheel, substantially as hereinset forth.
